How many moles of oxygen are present in a cylinder of 25.0 liters at a temperature of 0. °C and a pressure of 1.00 atm
Akimi4 [234]

Answer:

1.12 moles

Explanation:

To find the amount of moles, you need to use the Ideal Gas Law:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

After converting the temperature from Celsius to Kelvin, you can plug the given values into the equation and solve for "n".

P = 1.00 atm                     R = 0.08206 atm*L/mol*K

V = 25.0 L                        T = 0. °C + 273 = 273 K

n = ? moles

PV = nRT

(1.00 atm)(25.0 L) = n(0.08206 atm*L/mol*K)(273 K)

25.0 = n(22.4)

1.12 = n
